    i see no Problems... do you install openmediavault-md from system/extras?


    my cat /etc/mdadm/mdadm.conf show


    ARRAY /dev/md/0 metadata=1.2 UUID=cae6820a:792fec63:d14f8032:77ad4cf1 name=debian:0

    ARRAY /dev/md/1 metadata=1.2 UUID=f9db66ba:05a7bc16:cd5f7b20:93c53179 name=debian:1

    and cat /proc/mdstat

    I did the same thing.


    I installed a bare Debian setup, configured md-raid, and then installed OpenMediaVault. The array was listed.

    Afterwards, I added the filesystem(btrfs) in OpenMediaVault and mounted it.

    The plugin for managing software RAID, OpenMediaVault-md, is not installed.
